i have a function to this
var strip_tags = function(str,tags,attrs){
var reg2 = /\s*(\w+)=\"[^\"]+\"/gm;
var reg = /<\s*(\w+).*?>/gm;
str = str.replace(reg,function(match, i) {
var r_ = match;
var reg_ = /<\s*(\w+).*?>/gm;
var m_ = reg_.exec(match);
if(m_!=null){
if(tags.indexOf(m_[1])>=0){
r_ = match.replace(reg2,function(match_, i) {
var reg2_ = /\s*(\w+)=\"[^\"]+\"/gm;
var m = reg2_.exec(match_);
if(m!=null){
if(attrs.indexOf(m[1])>=0){
return match_;
}
}
return '';
});
}else{
r_ = '';
}
}else{
r_ = '';
}
return r_;
});
var reg3 = /<\/\s*(\w+).*?>/gm;
str = str.replace(reg3,function(match, i) {
var r_ = match;
var reg_ = /<\/\s*(\w+).*?>/gm;
var m_ = reg_.exec(match);
if(m_!=null){
if(tags.indexOf(m_[1])>=0){
return match;
}
}
return '';
});
return str;
};
tinyMCE.init(
...
plugins: "paste...
paste_preprocess : function(pl, o) {
var allowed_tags = ['ul','li','b','p','table','tr','td'];
var allowed_attributes = ['href','colspan','rowspan'];
o.content = strip_tags(o.content,allowed_tags,allowed_attributes);
},
...
);
